you are embedding the data into SQL statements? sort of like steganography?

you're dead from the outset

the first step would be the CREATE TABLE statement

you will be unable to come up with one SQL statement that can run on all databases

well, you might be able to, but you'll be using a very small subset of the broad range of datatypes that various database systems support

take TINYINT, for instance... in ANSI SQL this would have to be SMALLINT because there is no TINYINT

TEXT would be very problematic, as the ANSI SQL equivalent is CHARACTER LARGE OBJECT, but not every database system supports that syntax

and so on...

distributing a CSV would seem like a far simpler strategy -- users who have databases will know how to load it, and users who don't have databases (e.g. they have excel) can also use it
